STEEL-WOOL MACHINE.

' Application filed June 5, 1925. Serial No. 35,155.

My invention relates to steel wool machines and in particular to meansforconveying away the strands of steel wool there- 5 a 1 It is theobject of my invention to provide means for engaging the delicate steelwool strands and for moving them at a predetermined desired speed awayfrom thesteel wool machine as they are manufactured in 10 such away asto move them positively without injuring the strands. a

' a It is a furthr' object of my invention to provide means of enga'gingw'ith the, strands so as not to break them but to still frictional- 15ly engage them in .such a waythat the pull onthestrands'to removethenrfrom the machine will be uniform, constant and steady so that thestrands will not be broken.

Referring to the drawings: r v -F'gu'r'e '1 is a side elevation of oneform of the steel wool removing apparatus of my invention locatedadjacent to a diagrammatic illustration of a typical steel wool machine;Figure2 is a planview of one end of the 25 removing means shown inFigure 1; a Figure 3 is a'section on the line 33 of- Figure 1 showingthesupporting bracket broken, away and the supporting shafts in sectionwith a strand of steel. wool passing between the steel wool actuatingmembers;

. Fi ured is. a similar view on the line 4-4 of"Figure 5showi'ng amodified form of the steel wool removing means;

.ofathis removing'means consisting of spaced re s; a a

Figure 6 isan end elevation of another form of steel "wool removingmeans using solid rolls which frictionally engage with the steelWool-strands passing between them; v

Figure 7 is a'plan view of. this modified form illustrated; 1' Referringto the drawings in detail, 1 -1 are standards for, supporting the steel.wool 'maehinetable, 2 on either end of which is mounted the supportingbrackets consisting of the upright members 3 which terminate in spacedmembers 4, thus forming Y-shaped brackets at'either endof themachine. Itwill be understood that this steel wool removing means'may be locatedanywhere, that -is,above, below" or at one side of the'steel woolma'chine but for the purpose of illustration and th'e ease thereof, 1have shown it in a typical satisfactory form above the Figure-5 is aplanview of a modified form lmachinei Journaledin the ends'of these arms 1of the Y-shaped bracket are the shafts .5 and 6 which are thus supportedin parallel relationship. On one of these shafts is mounted a pulley 7actuated by a belt 8 from carry, on suitable end supporting members orplates 11 corrugated drums 12, such corrugations being formed as roundtopped ridges :13 which are relatively widely spaced with deep Valleys14 therebetween.

These two corrugated drums have their projecting corrugations or ridges13 adapted to project within the corresponding valleys 14 on the othercorrugated drum but the drums are so positioned through the gearing 9and 10 that while successive ridges project into opposite successivevalleys, yet the drums do not touch each other but are spaced 1.TllllClGllll distance between their adjacent surfaces to accomo datethe-steel wool strands 15 passing from the steel wool cutting tools 16.These strands. are fed between the corrugated rolls and are bent inserpentine form as they pass between the corrugations of the rolls wherethe corrugations of the rolls are adjacent, thus providing a frictionalengagement for movlng the strands. The strands are therefore moved bythis engagement at a predetermined speed without jerking or pulling andwithout rupture of the strands but they are nevertheless positivelymoved. The strands are easily examined as they are thus moved from themachine enablingthe operator to make the adjustments on the cuttingtools as may be desired.

These strands are out from the wire 17 passed lover thedrums 18 in theusual manner. These drums are mounted on the table 2 on theverticalspindles 19. It will be unin the case of the forms shown in Fiuresl,

2 and 3, not touching each other andbeing sufiiciently spaced toaccomodate the steel wool strand which is frictionally engagecljgy therods and moved away from the tools.

Referring to the form shown in Figures 6 and 7, it will be observed thatthe mech anism is the same save that two solid, smooth-faced rolls 23are employed WhlCll are suiiiciently spaced to a mmute degree not 7 toengage one another but to insure frictional engagement with the finestrands of wool which pass therebetween.

It will be understood that I desire to comprehend within my inventionsuch modifications as ma be necessary to adapt it to varying con itions'Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent, is

1. In a steel wool machine, cutters for said steel wool machine, meansfor feeding a wire to said cutters whereby a plurality of individualstrands of steel wool are cut simultaneously by said cutters from said bwire, means to remove steel wool strands from the cutters consisting ofa pair of synohronously. moving, .closely ad acent steel wool engagingmembers adapted to frictionally engage the wool strands individually topull them away from the cutters, said friction engagin members havingmeans for grasping said steel wool strands where by only-the, deadweight of the wool strands is lifted by said friction engaging memberswithout tension.
